In aging Japan, the key points to solve the shortage of manpower are as follows. Therefore, some young people in other countries, because the overall treatment in Japan is still very good, so many foreign young people will consider going to work in Japan, and because of the serious aging in Japan, there are also regulations that they can work until they are 70 years old, that is, to extend their working hours. In addition, Japan's equipment is relatively sound, and some equipment can basically be semi-automated, so fewer people are needed. These are the main solutions to the shortage of manpower in Japan.
